I think you are both right ?
I got the Ferodo connection fro Wikipedia
http://en.wikipedia.org/wiki/Valeo" onclick="window.open(this.href);return false; which says they distributed their parts under that name, rather than being part of Frerodo, my misreading of the article.
It is true that most parts these days, and in the past it seems, are usually only licensed rather than made by a particular brand name. I reckon the old days of manufactures with their own factories everywhere manufacturing parts are gone.
Most now seem to put their name on products they have made anywhere and everywhere.
Not a bad thing as long as they control the quality of what they put their name to.
I don't have a problem with who makes them as log as they are good quality, I assume Valeo are as they seem popular.
Often it is one factory making parts under several names. I remember a friend saying he believed elctronics parts from Japan were often allocated as follows. One factory makes a part, the prestige local companies buy those above specification so their products are reliable and good quality. Good companies buy those in specification and cheaper companies buy the ones which are below spec but still saleable, may not last but very cheap.
I guess the moral is buy from one of the first two companies
